Item Orthopaedics and Biomedical Engineering Design: An Innovative Duet toward a Better Tomorrow(Journal of the Pediatric Orthopaedic Society of North America, 2023-05-01) Su, Alvin W.; Khandha, Ashutosh; Bansal, Sonia; Ty, Jennifer M.; Baldys, Andrew; French, Zachary P.; Puccinelli, John P.The main purpose of this article is to explore the benefits and dynamics of collaborations between orthopaedic surgeons and biomedical engineering (BME) undergraduates and faculties in the context of engineering design programs as well as clinical immersion programs. An outline of strategies to navigate the seemingly complex landscape of hospitals and universities is presented through models of orthopedic-BME collaborations at two distinct academic practice settings in the United States. In addition to (four) examples of BME design projects sponsored by the clinicians, funding and intellectual property (IP), priority of time management, as well as the positive impact on student education are also discussed. Design collaborations can provide unique educational and research opportunities for the development of undergraduate engineering students to become future leaders; at the same time, this simultaneously facilitates innovative solutions fulfilling unmet clinical needs for orthopedic clinicians. Overall, we hope to provide references and resources for those who are interested in developing similar orthopedic-BME design framework for future innovation and student education in real-life orthopedic research translation.Item Surgical Management of Traumatic Meniscus Injuries(Pathophysiology, 2023-12-04) Popper, Hannah R.; Fliegel, Brian E.; Elliott, Dawn M.; Su, Alvin W.The menisci increase the contact area of load bearing in the knee and thus disperse the mechanical stress via their circumferential tensile fibers. Traumatic meniscus injuries cause mechanical symptoms in the knee, and are more prevalent amongst younger, more active patients, compared to degenerative tears amongst the elderly population. Traumatic meniscus tears typically result from the load-and-shear mechanism in the knee joint. The treatment depends on the size, location, and pattern of the tear. For non-repairable tears, partial or total meniscal resection decreases its tensile stress and increases joint contact stress, thus potentiating the risk of arthritis. A longitudinal vertical tear pattern at the peripheral third red-red zone leads to higher healing potential after repair. The postoperative rehabilitation protocols after repair range from immediate weight-bearing with no range of motion restrictions to non-weight bearing and delayed mobilization for weeks. Pediatric and adolescent patients may require special considerations due to their activity levels, or distinct pathologies such as a discoid meniscus. Further biomechanical and biologic evidence is needed to guide surgical management, postoperative rehabilitation protocols, and future technology applications for traumatic meniscus injuries.
